The presidential election of 2004 brought Ukraine to the brink of disintegration and civil war. Cleared to seek a third term as president by the Constitutional Court, Kuchma instead endorsed the candidacy of Prime Minister Viktor Yanukovych, who was also strongly supported by Russian Pres. Vladimir Putin. Yushchenko—running on an anticorruption, anticronyism platform—emerged as the leading opposition candidate, but his campaign was prevented from visiting Yanukovych’s stronghold of Donetsk and other eastern cities. In September Yushchenko’s health began to fail, and medical tests later revealed he had suffered dioxin poisoning (allegedly carried out by the Ukrainian State Security Service), which left his face disfigured. In the first round of the presidential election, on October 31, Yushchenko and Yanukovych both won about two-fifths of the vote. In the runoff the following month, Yanukovych was declared the winner, though Yushchenko’s supporters charged fraud and staged mass protests that came to be known as the Orange Revolution. Protestors clad in orange, Yushchenko’s campaign colour, took to the streets, and the country endured nearly two weeks of demonstrations. Yanukovych’s supporters in the east threatened to secede from Ukraine if the results were annulled. Nevertheless, on December 3 the Supreme Court ruled the election invalid and ordered a new runoff for December 26. Yushchenko subsequently defeated Yanukovych by garnering some 52 percent of the vote. Although Yanukovych challenged the validity of the results, Yushchenko was inaugurated on January 23, 2005.

Political turmoil occupied the first few years of Yushchenko’s presidency. His first cabinet served only until September 2005, when he dismissed all his ministers, including Prime Minister Yuliya Tymoshenko, a fellow leader of the Orange Revolution. The next prime minister, Yury Yekhanurov, stayed in office only until January 2006. Parliamentary elections early that year saw Yushchenko’s Our Ukraine party finish third, behind Yanukovych’s Party of Regions and the Yuliya Tymoshenko Bloc. When a proposed coalition of the so-called Orange parties in the parliament fell apart, Yushchenko was forced to accept his rival Yanukovych as prime minister. The ensuing power struggle between the president and the prime minister, whose political role had been enhanced by a constitutional reform that took effect in 2006, led Yushchenko to call for another round of parliamentary elections in 2007. Once again the president’s party finished behind both Yanukovych’s and Tymoshenko’s parties. This time, however, a coalition with the Yuliya Tymoshenko Bloc held together, allowing the pro-Western Orange parties to form a government with Tymoshenko as prime minister. As the government continued to balance the often conflicting goals of maintaining positive relations with Russia and gaining membership in the EU, dissent between Yushchenko and Tymoshenko contributed to the collapse of their coalition in September 2008. In October the president dissolved parliament. Parliamentary elections, at first scheduled for December, later were canceled, and Yushchenko’s and Tymoshenko’s parties agreed to form a new coalition, together with the smaller Lytvyn Bloc, headed by Volodymyr Lytvyn.

The next presidential election, held on January 17, 2010, confirmed the political demise of President Yushchenko, who received only about 5 percent of the vote. The top two candidates, Yanukovych and Tymoshenko, garnered about 35 and 25 percent, respectively. Because neither had won a majority of votes, a runoff poll was held on February 7. The runoff results were split largely along regional lines, with most of western Ukraine supporting Tymoshenko and most of the east favouring Yanukovych. Winning 48.95 percent of the vote—a narrow lead over Tymoshenko’s 45.47 percent—Yanukovych took the presidency. Although international observers determined that the poll had been fair, Tymoshenko declared the results fraudulent and refused to recognize Yanukovych’s victory; she and her supporters boycotted the inauguration of Yanukovych on February 25. The following week Tymoshenko’s government was felled by a vote of no confidence and Mykola Azarov of the Party of Regions was installed as prime minister. President Yanukovych gained greater executive authority later in 2010 when the Constitutional Court overturned the 2006 reform that had enhanced the powers of the prime minister.

In April 2010, following a fractious parliamentary debate, Ukraine agreed to extend Russia’s lease of the port at Sevastopol, originally set to expire in 2017, until 2042. In exchange, Ukraine would receive a reduction in the price of Russian natural gas. The Ukrainian government further improved relations with Russia in June 2010, when it officially abandoned its goal of joining NATO—a pursuit Russia had opposed. As the Yanukovych administration continued its pivot towards Moscow, EU leaders expressed concern about the preservation of the rule of law in Ukraine.

In 2011 former prime minister Tymoshenko, the country’s most popular politician, was convicted of abuse of power in connection with a 2009 natural gas deal with Russia and given a seven-year prison sentence. In February 2012 Tymoshenko’s interior minister, Yuri Lutsenko, also was convicted of abuse of power and sentenced to four years in prison. Many observers believed both trials were politically motivated. When Ukraine cohosted the UEFA European Championshipfootball (soccer) tournament in summer 2012, a number of EU countries registered their concern for Tymoshenko by boycotting the event.

In the parliamentary election in October 2012, the ruling Party of Regions emerged as the single largest bloc, with 185 seats. Tymoshenko’s Fatherland party claimed 101 seats, Vitali Klitschko’s Ukrainian Democratic Alliance for Reforms (UDAR) won 40 seats, and the ultranationalist Svoboda (“Freedom”) party had a surprisingly strong showing, winning 37 seats. Challenging the validity of the results, Tymoshenko embarked on a hunger strike. Although international observers called attention to irregularities in some contests, the European Parliament characterized the election as comparatively fair, and the main opposition parties accepted the official results. In December 2012 sitting Prime Minister Azarov formed a government with the support of Communist and independent deputies. In what was widely seen as an attempt to thaw relations with the EU, Yanukovych pardoned the imprisoned Lutsenko and ordered his release in April 2013.
